Thanks mrgreenspeed. I fabricated coro struts with coat hanger internal spar. will see if that does it. I also stripped some wire and wrapped the ingnition coil wire and grounded it to see if that helps with the interference. I aso removed the kill switch. Hopefully will get to rangecheck it today. If that doesn't work, I made need to get nylon 1/4 inch bolts to attach the engine plate to the firewall to eliminate that metal on metal contact.
